We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction. As an example, we examine the code built from quantum chromodynamics, where the proton and neutron states in the model are explored as different superselection sectors that protect logical information. Finally we comment on topological quantum error correcting codes and supersymmetric quantum field theory within this framework.application/pdfenCreative Commons Attribution 4.0 InternationalArticle - Refereed2025-06-01The Author(s)https://doi.org/10.1007/JHEP05(2025)236
